Luke Kendrick, 26, and Ryan Bate, 24, deny Vinny’s murder and the wounding with intent to cause GBH of his friend, Francis Humphries.

The jury must now decide whether Bate and Kendrick were inside Kendrick’s Audi A3 car when a single shotgun blast was fired from the driver’s window on July 14, killing Vinny and wounding Mr Humphries.

Vinny, 18, had been the pillion passenger on a scrambler motorbike, driven by Mr Humphries, which was struck by the Audi in Banks Road, Garston , seconds before the shooting.

Judge King yesterday told the jury it “matters not” who pulled the trigger, but said there had to have been an “agreement” among the men in the car to cause really serious bodily harm for them to reach a guilty verdict.

The jury were presented with three questions in a Route to Verdict document which they must answer to decide the fates of Kendrick and Bate.

The questions are:

Are we sure that the person who fired the shot from the Audi motor car which fatally wounded Mr Waddington did so with intention to cause at least really serious bodily harm to someone?

Are we sure that the defendant was in the car at the time knowing the shooter had a gun that was loaded, and was giving the shooter some kind of assistance or encouragement to fire the gun?

Are we sure that defendant gave such assistance with the intention that at least really serious bodily harm be caused to someone?

Mr Justice King told the jury they must consider each one of these questions separately for each defendant.

He said if any of the answers for a particular question is no, then that defendant is not guilty of murder.

Kendrick and Bate both deny being in the car at the time of the shooting.

But prosecution say Kendrick admitted being in the car during a rant filmed on police body cam, in which he appeared to say he had “rammed” the victims off their bike.

However Kendrick claimed in court he had passed his car to three men minutes before the murder, who offered to “sort out” lads on scrambler bikes that had been causing problems.

He said he had lied to police out of “fear” of being a grass.”

Bate, whose mobile phone was found in the car, is alleged to have been on one end of a 56 second phone call received at 8.42pm, when the actual murderer would have to have been in the car.

However he said he had been dropped off at his girlfriend’s house around 10 minutes before the murder, and left his phone in the car.

A third man, David Ungi jnr, is alleged to have been in the car at the time of the murder but has yet to be arrested after leaving the country.
